This is due to missing or incorrect nonce validation on the uss_setting_page function when processing the uss_set form type. This makes it possible for unauthenticated attackers to modify critical Upyun cloud storage settings including bucket name, operator credentials, upload paths, and image processing parameters via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
